In addition, the light-emittingunit 104 a, light-emitting unit 104 b, and light-emitting unit 104 c mayserve as subpixels. In some embodiments, the light-emitting unit 104 a,light-emitting unit 104 b, and light-emitting unit 104 c may emit redlight, green light and blue light respectively, but it is not limitedthereto. In some other embodiments, at least one of the pixels P mayinclude, but is not limited to, four subpixels (light-emitting unit 104)for emitting red light, green light, blue light and yellow light, or foremitting red light, green light, blue light and white light.

In some embodiments, the material of the first substrate 102 mayinclude, but is not limited to, glass, quartz, sapphire, polycarbonate(PC), polyimide (PI), polyethylene terephthalate (PET), rubbers, glassfibers, other polymer materials, any other suitable substrate material,or a combination thereof. In some embodiments, the first substrate 102may include a metal-glass fiber composite substrate, a metal-ceramiccomposite substrate, a printed circuit board, or any other suitablesubstrate, but it is not limited thereto.

In addition, the electronic device 10 may include an antenna 106disposed between the light-emitting units 104. The antenna 106 mayreceive and/or transmit the electromagnetic wave. The antenna 106 may beelectrically connected to a controller 108 (e.g., as shown in FIG. 5) inaccordance with some embodiments. More specifically, the antenna 106 mayreceive the electromagnetic wave from the environment and generateinduced current to the controller in the electronic device 10. Thecontroller may also control the current flowing to the antenna 106 totransmit the electromagnetic wave.

In some embodiments, the material of the antenna 106 may includeconductive materials. In some embodiments, the conductive material mayinclude, but is not limited to, copper, aluminum, molybdenum, tungsten,gold, chromium, nickel, platinum, titanium, silver, copper alloys,aluminum alloys, molybdenum alloys, tungsten alloys, gold alloys,chromium alloys, nickel alloys, platinum alloys, titanium alloys, silveralloys, any other suitable conductive materials (e.g., carbonnano-tubes), or a combination thereof In some embodiments, the materialsof the antenna 106 may include transparent conductive materials. Forexample, the transparent conductive material may include, but is notlimited to, indium tin oxide (ITO), tin oxide (SnO), indium zinc oxide(IZO), indium gallium zinc oxide (IGZO), indium tin zinc oxide (ITZO),any other suitable transparent conductive materials, or a combinationthereof. In some embodiments, the materials of the antenna 106 mayinclude conductive polymers. For example, the conductive polymer mayinclude, but is not limited to, poly (3,4-ethylenedioxythiophene),polystyrene sulfonate (PEDOT:PSS), polythiophenes (PT), polypyrrole(PPY), polyphenylene sulfide (PPS), or a combination thereof. Inaddition, the antenna 106 may be a single layered structure, or amultiple layered structure.

In some embodiments, at least a portion of the antenna 106 may have afirst width W₁. In some embodiments, a distance between two adjacentlight-emitting units 104 that are located at opposite sides of theantenna 106 may be a first distance D₁. In one example where thelight-emitting units 104 are bare-die light-emitting diodes, the firstdistance D₁ is the distance between the bare dies (i.e. without packagestructures) of the two adjacent light-emitting units 104. In otherexamples where the light-emitting units 104 are packaged light-emittingdiodes, the first distance D₁ is the distance between the packages ofthe light-emitting units 104. In some embodiments, the ratio of thefirst width W₁ to the first distance D₁ may be ranged from about 0.1 toabout 0.8, or from about 0.2 to about 0.6, such as 0.3, 0.4, or 0.5. Inparticular, if the ratio of the first width W₁ to the first distance D₁is too small (e.g., less than about 0.1), the performance of the antenna106 may be poor due to high resistance. On the other hand, if the ratioof the first width W₁ to the first distance D₁ is too large (e.g.,greater than about 0.8), the antenna 106 may reflect light and thus thevisual effect of the electronic device 10 may be affected.

Specifically, the first width W₁ may be the maximum width of the antenna106 on the plane that is substantially perpendicular to the normaldirection of the first substrate 102, e.g., the X-Y plane, as shown inFIG. 1. It should be understood that the width of the antenna 106described herein may refer to the width of the antenna 106 that isdisposed between two adjacent light-emitting units 104 in a displayregion of the electronic device 10 (e.g., as shown in region B of FIG.8). Moreover, the first distance D₁ may refer to the minimum distancebetween two adjacent light-emitting units 104 that are located atopposite sides of the antenna 106. For example, as shown in FIG. 1, thefirst distance D₁ may refer to the minimum distance between twolight-emitting units 104 a, two light-emitting units 104 b, or twolight-emitting units 104 c that are located at opposite sides of theantenna 106.

More specifically, in the embodiments where the antenna 106 includesseveral line segment portions, the width of the antenna 106 may refer tothe width that is substantially perpendicular to the extending directionof the line segment portion. For example, as shown in FIG. 1, theantenna 106 may include a first portion 106 a that extends in anextending direction substantially the same as or different from theX-axis (e.g., the first direction E₁). The width of the first portion106 a of the antenna 106 may refer to the width that is substantiallyperpendicular to the extending direction.

On the other hand, in the embodiments where the antenna 106 includescurved portions, the width of the antenna 106 may refer to the widththat is substantially perpendicular to a tangent T of the curvedportion. For example, refer to FIGS. 2A and 2B, which are top-viewdiagrams of the antenna 106 in accordance with some embodiments of thepresent disclosure. The antenna 106 may include one or more curvedportions 106 r. The width W of the curved portion 106 r of the antenna106 may refer to the width that is substantially perpendicular to thetangent T of the curved portion 106 r.

In addition, referring to FIG. 1 again, the antenna 106 may include thefirst portion 106 a extending along a first direction E₁ and a secondportion 106 b extending along a second direction E₂ different from thefirst direction E₁ in accordance with some embodiments. In otherembodiments, the antenna 106 may include other portion(s) extendingalong other direction(s), but it is not limited thereto. The first widthW₁ of the first portion 106 a may be the same as or different from asecond width W₂ of the second portion 106 b. In some embodiments, thefirst width W₁ of the first portion 106 a may be greater than the secondwidth W₂ of the second portion 106 b. In some embodiments, the firstdistance D₁ may refer to a subpixel distance between two adjacentsubpixels (light-emitting units 104). As shown in FIG. 1, the firstdistance D₁ corresponding to the first portion 106 a may be greater thana second distance D₂ corresponding to the second portion 106 b. Morespecifically, the first distance D₁ between two adjacent subpixels thatare located at opposite sides of the first portion 106 a may be greaterthan the second distance D₂ between two adjacent subpixels that arelocated at opposite sides of the second portion 106 b. The antenna 106may include a turning portion 106 t disposed between two portions (e.g.,the first portion 106 a and the second portion 106 b), but it is notlimited thereto. In some examples, the turning portion may connect thefirst portion 106 a and the second portion 106 b.

In some embodiments, a gap distance may refer to the minimum distancebetween the antenna 106 and the light-emitting units 104. In addition,the gap distance may be the distance between the antenna 106 and thebare die of the light-emitting unit, or the distance between the antenna106 and the package of the light-emitting unit 104, depending on thetype of the light-emitting unit 104, but it is not limited thereto. Asshown in FIG. 1, in some embodiments, the first gap distance G₁corresponding to the first portion 106 a may be greater than a secondgap distance G₂ that corresponds to the second portion 106 b. Moreover,in some embodiments, the ratio of a first gap distance G₁ to the firstdistance D₁ may be ranged from about 0.05 to about 0.75, or from about0.25 to about 0.75, such as 0.3, 0.35, 0.4, 0.45, 0.5, 055, 0.6, 0.65,or 0.7.

It should be noted that if the ratio of the first gap distance G₁ to thefirst distance D₁ is too small (e.g., less than about 0.05) or too large(e.g., greater than about 0.75), the antenna 106 may be too close tosome of the light-emitting units 104 and may affect the performance ofthe electronic device 10. In some embodiments, the antenna 106 mayoverlap a midpoint M of the first distance D1 between two adjacentlight-emitting units 104, and thus the antenna 106 may not be too closeto or too far from the light-emitting units 104. The term “overlap” mayrefer to partially overlap or entirely overlap in the normal directionof the first substrate 102 in the present disclosure.

Moreover, in some embodiments, the ratio of the first width W₁ of theantenna 106 to a width W_(L) of one of the light-emitting units 104 maybe ranged from about 0.4 to about 100, or from about 0.6 to about 75,such as 0.6, 5, 20, or 50. In particular, if the ratio of the firstwidth W₁ to the width W_(L) is too small (e.g., less than about 0.4),the performance of the antenna 106 may be poor due to high resistance.On the other hand, if the ratio of the first width W₁ to the width W_(L)is too large (e.g., greater than about 100), the antenna 106 may reflectlight and the display quality of the electronic device 10 may beaffected.

In one example where the light-emitting unit 104 is a bare-dielight-emitting diode, the width W_(L) of the light-emitting unit 104 mayrefer to the maximum width of the bare die. In other examples where thelight-emitting unit 104 is a packaged light-emitting diode, the widthW_(L) of the light-emitting unit 104 may refer to the maximum width ofthe package. In addition, the maximum width may be the farthest distancebetween two points on the boundary or profile of the bare die of thelight-emitting unit 104. In embodiments where the profile of thelight-emitting unit 104 has obvious corners, the width W_(L) of thelight-emitting unit 104 may refer to the maximum distance between twocorners. For example, refer to FIGS. 2C and 2D, which are top-viewdiagrams of the light-emitting unit 104 in accordance with someembodiments of the present disclosure. The width W_(L) of thelight-emitting unit 104 may refer to the maximum distance between twocorners C of the profile of the light-emitting unit 104. On the otherhand, in embodiments where the profile of the light-emitting unit 104does not have obvious corners, the width W_(L) of the light-emittingunit 104 may be obtained by actual measurement of the maximum distancebetween two points of the profile, as shown in FIG. 2E.

Referring to FIG. 1, in some embodiments, the antenna 106 may furtherinclude several first portions 106 a extending along the first directionE₁ and several second portions 106 b extending along the seconddirection E₂. In some embodiments, the first portions 106 a and thesecond portions 106 b may be connected to form a continuous structure.In some embodiments, the antenna 106 may include several spiral or loopstructures. As shown in FIG. 1, the antenna 106 may have a helical shapeor a spiral shape in accordance with some embodiments. In addition, thehelical or spiral shape may be left-handed or right-handed.

Next, refer to FIG. 3, which is a top-view diagram of an electronicdevice 20 in accordance with some other embodiments of the presentdisclosure. In should be understood that the same or similar componentsor elements in the context of the descriptions provided above and beloware represented by the same or similar reference numerals. Thematerials, manufacturing methods and functions of these components orelements are the same as or similar to those described above, and thuswill not be repeated herein. As shown in FIG. 3, the antenna 106 may bedisposed between two adjacent pixels P in accordance with someembodiments. Moreover, the antenna 106 may not be disposed between twoadjacent subpixels (e.g., between the light-emitting units 104 a and 104b, or between the light-emitting units 104 b and 104 c) in accordancewith some embodiments. In other words, the pixel P may not beinterrupted by layout of the antenna 106 in accordance with someembodiments. In particular, since one pixel P may serve as a unit fordisplay, the antenna 106 disposed between the pixels P rather thanbetween the subpixels may have better display quality.

In some embodiments, the antenna 106 may include turning portions 106 t.The turning portion 106 t may be located at the position where theextending direction of the antenna 106 is changed. For example, as shownin FIG. 3, the turning portion 106 t may be located at the positionwhere the first portion 106 a is connected to the second position 106 b,i.e. the position where the extending direction of the antenna 106 ischanged from the first direction E₁ to the second direction E₂. In someembodiments, the turning portion 106 t may also be disposed between thepixels P, rather than between the subpixels (e.g., between thelight-emitting units 104 a and 104 b, or between the light-emittingunits 104 b and 104 c). In addition, in some embodiments, one pixel Pmay include N subpixels (light-emitting units 104), i.e. the number ofsubpixels is N. In some embodiments, the first portion 106 a may passthrough or pass by N x n subpixels (i.e. the amount of subpixels is Ntimes n), wherein n refers to any positive integer. For example, asshown in FIG. 3, the pixel P may include three subpixels, and the firstportion 106 a may pass through or pass by 3n subpixels, e.g., 3, 6, 9,12, 15 subpixels in accordance with some embodiments.

As shown in FIG. 4, in some embodiments, the electronicdevice 30 may include a plurality of first portions 106 a and aplurality of second portions 106 b that are connected to enclose some ofthe light-emitting units 104. More specifically, several first portions106 a and several second portions 106 b may be connected together toform a combined first portion 106 a′ and a combined second portion 106b′. In some embodiments, the combined first portion 106 a′ may extend inthe first direction E₁, and the combined second portion 106 b′ mayextend in the second direction E₂. In some embodiments, some of thesecond portions 106 b may be disposed between subpixels. In someembodiments, the antenna 106 that includes part of the combined firstportion 106 a′ or part of the combined second portion 106 b′ may bedisposed between subpixels. The combined first portion 106 a′ and thecombined second portion 106 b′ may increase the area of the antenna 106in the electronic device 30, and the resistance of the antenna 106 maybe reduced.

In some embodiments, the combined first portion 106 a′ and the combinedsecond portion 106 b′ may include openings 107 disposed therein. Thelight-emitting units 104 may be disposed in the openings 107. In someembodiments, the opening 107 may be surrounded by the first portions 106a and the second portions 106 b. Although one opening 107 may encompassone light-emitting unit 104 in the embodiment shown in FIG. 4, oneopening 107 may encompass more than one light-emitting units 104 inaccordance with some other embodiments. In other words, the numbers ofthe first portions 106 a and the second portions 106 b in the combinedfirst portion 106 a′ or the combined second portion 106 b′ may beadjusted depending on need in various embodiments.

In some embodiments, the combined first portion 106 a′ and the combinedsecond portion 106 b′ may be formed by using one or more depositionprocesses, photolithography processes and etching process. In someembodiments, the deposition process may include a chemical vapordeposition process, a physical vapor deposition process, anelectroplating process, an electroless plating process, another suitableprocess, or a combination thereof.

In addition, as described above, the antenna 106 may be electricallyconnected to a controller 108 to receive and/or transmit theelectromagnetic wave. In some embodiments, the controller 108 mayinclude a driving element, a signal processer or a combination thereof.For example, the antenna 106 may receive the electromagnetic wave fromthe environment and generate induced current to the signal processer.The signal processor may then transmit signals to the driving element tocontrol the current flow of the antenna 106. In some embodiments, thedriving element may include an active driving element, a passive drivingelement and/or a combination thereof. For example, the active drivingelement may include a thin-film transistor (TFT). In some embodiments,the active driving element may be integrated with the circuit of a gateon array (GOP) structure. The passive driving element may be controlledby an IC or a microchip disposed in or outside the electronic device 10.In some embodiments, the IC may control the antenna 106 and signalslines (e.g., data lines and scan lines) at the same time.

It should be understood that although the loop structure 106 p has asquare shape in the embodiments shown in FIG. 5, the loop structure mayhave another suitable shape, such as a circular shape, a diamond shape,and so on depending on need, in accordance with some other embodiments.

Insome embodiments, the turning portions 106 t may include a roundedcorner, an angled corner, or a combination thereof in accordance withsome embodiments. In one example, the rounded corners may have differentradius of curvature. In particular, the rounded corner, or angled cornerlocated at the turning portions 106 t may reduce the risk of occurrenceof corona discharge, and the performance of the antenna 106 may beimproved.

In some embodiments, the rounded corner, or the angled corner of theantenna 106 may be formed by using a photolithography process, anetching process, a grinding process, a polishing process, or acombination thereof.

Inother words, the width of the first portion 106 a may be inconsistent.The width of the second portion 106 b may be inconsistent. Specifically,in some embodiments, the electronic device 60 may include a circuitlayer (as shown in FIGS. 10A-10D) disposed on the first substrate 102 orother metal lines disposed on another layers, the recessed portions Rmay correspond to the positions of theses circuit layer or metal lines.The recessed portions R may reduce the overlapping area between thecircuit layer (or other metal lines) and the antenna 106. With such aconfiguration, the issues of signal interference, capacitive couplingand so on may be reduced in the electronic device 60. In someembodiments, the metal lines may include signal lines for controllingthe light-emitting units 104.

In some embodiments, the recessed portion R of the antenna 106 may beformed by using photolithography processes, etching process, or acombination thereof.
